以苯并三唑（BTA）为母体合成了两种双苯并三唑Mannich碱1,2-双([1,2,3]苯并三唑)-1,2-二苯基氨基乙烷(BBTAP)和1,2-双([1,2,3]苯并三唑)-1,2-二甲基氨基乙烷(BBTAM)。采用静态失重法、极化曲线和电化学阻抗谱（EIS）研究了 BBTAP、BBTAM和BTA在5 mass% NaHCO3水溶液中的缓蚀性能和吸附行为。结果表明：在较高温度下，三种化合物在5% NaHCO3溶液中对Cu均有较好的缓蚀作用。与BTA相比，BBTAP和BBTAM具有用量少，缓蚀效率高的特点。三种化合物在铜表面上的吸附过程均为放热过程，在铜表面上的吸附行为服从 Langmuir吸附等温式，属于物理--化学混合吸附。。
Two bis-benzotriazole Mannich alkali compounds, 1,2-di(1H-benzo[d][1,2,3] triazol-1-yl)-N1,N2-diphenylethane-1,2-diamine (BBTAP) and 1,2-di(1H-benzo[d][1,2,3] triazol-1-yl)-N1, N2-dimethylethane-1, 2-diamine (BBTAM), were synthesized using benzotriazole (BTA) as matrix. The inhibition actions and adsorption behaviors of BBTAP, BBTAM and BTA on copper in aqueous NaHCO3 (mass fraction 5%) solution were investigated by means of mass loss and electrochemical techniques including polarization curve and electrochem-ical impedance spectroscopy (EIS). The results showed that BBTAP, BBTAM and BTA exhibited good inhibition effect for copper in 5% NaHCO3 solution at higher temperature and BBTAP, BBTAM had better corrosion inhibition efficiency than that of BTA. The results of experiment revealed that the adsorption processes were exothermic reaction and belonged to physical and chemical mix absorption, the adsorption behaviors followed Langmuir isotherm.
